Stability and path co-efficient analysis for yield and its components in pigeonpea [Cajanus cajan (L.) Millsp.]
Abstract
A study was conducted to examine the stability and path analysis of the twenty advanced genotypes of pigeonpea including check WRP-1, during kharif-2012, 2013 and 2014 under irrigated condition at the Agricultural Research Station, Kalaburagi. Pod length (0.378, 1.612), pod bearing length (0.493, 1.043), secondary branches (0.314, 0.935) and number of pods per plant (0.362, 0.539)had the highest positive direct effect on grain yield both at genotypic and phenotypic level. For maximizing the grain yield per plant emphasis should be given in selection of such characters for further improvement in pigeonpea. Highly significant differences among varieties were observed for all the characters except primary branches. The variance due to genotype x environmental (G x E) interaction found to be significant for days to flower initiation, plant height number of seeds per pod and yield per plant. All the traits under the study except for 100 seed weight showed significant differences in different environment. The variance due to pooled deviation was highly significant for all the traits except for primary branches and number of seeds per pod which reflect considerable variability in the material. Out of 20 genotypes studied four entries viz., RVK-285, AKT-9913, JKM-189 and ICP-13579 were consistent and high yielding compared to local check for irrigated conditions.
